shooting after the scene, people go there, public firefighters and servants. the trauma surgeons, emergency physicians anesthesiologists, orthopedic surgeons, nurses, therapists and many, many others who come to help us work on the patient. and we do this for every single person who is injured. we bring all the resources there. we can to make sure we can save as many people as we can each day. the reality and sadness is we may save many, but we can't save everyone. over the years i have seen massive increase in the fire power witnesses before you today. these guns are more powerful and destruction are profound. from ak-47s, other assault-style weapons, hand gun, extended clips, hollow point bullets, black talon weapons, bullets and other things like that, i've seen them and the work that -- the problems they cause each day.
